  However, the thing of the said literature has a possibility that a grain may leak easily from the clearance gap between a rotation chute and a rubber drooping chute, and the leaked grain may fall from the loading platform of a truck. In addition, since the two rotating chutes are interlocked with a connecting rod and the one side (driving side) rotating shooter is rotationally driven by a motor pinion device or an extension cylinder, the grains are connected to the connecting rod and the rubber dripping chute. There is a disadvantage that the structure is complicated while being caught.

The present invention has been created in order to solve these problems in view of the above-described circumstances, and includes a grain tank that stores selected grains, and a grain in the grain tank. In a combine provided with a discharge auger that discharges outside, a discharge cover body that covers the lower periphery of the discharge port formed at the tip of the discharge auger is provided, and the grain that exits from the discharge port is lowered by the discharge cover body A guide plate that guides the grain along the inside of the distal side wall of the discharge governor body, the lower part of the guide plate can be pivoted away from the distal side wall with its upper end as a fulcrum, By changing the rotation position of the guide plate, the grain discharging direction can be changed to the auger base side, and the guide plate is configured to be rotatable with its upper end as a fulcrum, and the guide plate The bottom of Provided with a guide plate automatic turning means for changing the grain discharge direction by periodically reciprocatingly driving between the end side wall and the auger base side, turning on and off the guide plate automatic turning means, It is characterized by being linked to turning on and off of the transport spiral drive of the discharge auger .

According to the combine of the present invention configured as described above, the discharge cover body that covers the periphery of the discharge port is provided, and the rotatable guide plate is provided inside the distal side wall of the discharge cover body. Even though it is configured, the grain discharge direction can be changed to the auger transfer direction in the discharge cover body, and the labor of leveling the grain after being discharged to the truck bed is reduced. And even if the grain leaks from the gap between the guide plate and the discharge cover body, the grain is guided downward by the tip side wall of the discharge cover body, so that the grain can be prevented from falling from the loading platform of the truck.
Also, if the operation of the discharge auger is turned on and off at the time of grain discharge, the operation of the guide plate automatic turning means is automatically turned on and off, so there is no need to manually drive the reciprocating rotation of the guide plate, There is no need to turn on and off the operation of the automatic guide plate rotation means, further reducing the labor of the operator.

A grain discharge switch 25 that rotates the spiral 13 to discharge the grain via the discharge auger 11 is provided.

  The auger operating tool 24 is an operating lever for swinging back and forth and from side to side. An operator causes the auger to swing downward (down) by swinging the operating lever 24 backward with respect to the forward direction of the machine body, and causes the auger to swing upward (lift) by swinging forward. The auger is driven to turn left by swinging left (the left in the traveling direction), and the auger is driven to turn right by swinging right.

  The combine 1 is provided with a control unit 30 configured using a microcomputer (including a CPU, a ROM, a RAM, and the like). FIG. 6 is a block diagram showing the input / output of the control unit 30 that controls the rotation of the guide plate 15. The input portion of the control unit 30 includes a grain discharge switch 25 that performs a helical drive on / off operation of the discharge auger 11, and the guide plate 15 is automatically reciprocated in conjunction with the turning operation of the grain discharge switch 25. A guide plate automatic rotation switch 31 for performing an on / off operation of the guide plate automatic rotation control to be driven and a guide plate manual rotation switch 32 capable of operating the guide plate 15 to an arbitrary rotation position by manual operation are predetermined. The output auger is driven on the basis of the on / off operation of the grain discharge switch 25 and the electric motor M that rotationally drives the guide plate 15 described above. A discharge clutch drive motor to be turned on and off is connected via a predetermined output interface circuit. That is, the control unit 30 includes a control program such as a guide plate automatic rotation control that automatically drives the guide plate 15 to reciprocate based on an input operation of the grain discharge switch 25. The control procedure will be described with reference to a flowchart.

  FIG. 7 is a flowchart showing a processing procedure of guide plate control. In the guide plate control, first, it is determined whether or not the guide plate manual rotation switch 32 is turned ON / OFF in S1. Control is executed. On the other hand, when the manual rotation switch 32 is OFF, it is determined at S3 whether the grain discharge switch 25 is ON or OFF, and when the determination result is ON, whether the automatic rotation switch 31 is ON / OFF is determined at S4. On the other hand, when the grain discharge switch 25 is OFF, the process returns to the upper routine. When the automatic rotation switch 31 is ON in S4, automatic guide plate rotation control for automatically and periodically driving the guide plate 15 to reciprocate is executed. On the other hand, when the automatic rotation switch 31 is OFF, the process returns to the upper routine.

  Therefore, according to the guide plate control, when the guide plate automatic rotation switch 31 is pushed (input operation) and the guide plate automatic rotation control is executed, based on the input operation of the grain discharge switch 25. The guide plate 15 is automatically and reciprocally rotated periodically, and the reciprocating rotation drive of the guide plate 15 is stopped based on the turning operation of the grain discharge switch 25. On the other hand, when the guide plate automatic rotation switch 31 is OFF and the guide plate automatic rotation control is not executed, the guide plate 15 remains stopped even if the grain discharge switch 25 is turned on and off. That is, a guide plate automatic rotation means for periodically driving the guide plate 15 to reciprocate is constituted by the control unit 30, the guide plate automatic rotation switch 31, and the electric motor M.

  The guide plate control is also provided with manual rotation control based on the opening / closing operation of the guide plate manual rotation switch 32, and the guide plate manual rotation composed of a seesaw type switch that returns to the neutral position when the hand is released. When the switch 32 is opened (pressed), the electric motor M is driven in the opening direction and the guide plate 15 is rotated in the opening direction of FIG. On the other hand, when the guide plate manual rotation switch 32 is closed (pressed), the guide plate 15 is driven to rotate in the closing direction of FIG. 5 while the switch is being pressed. The rotation range of the guide plate 15 is restricted so that the guide plate 15 does not rotate in the closing direction beyond a predetermined angle from the side wall F on the front end side, thereby preventing the discharge clogging due to being closed in the closing direction. The turning range is the same as the reciprocating turning range of the guide plate 15 by the guide plate automatic turning control.

What is constituted as described above is a combine comprising a grain tank 4 for storing selected grains and a discharge auger 11 for discharging the grains in the grain tank 4 to the outside of the machine. 11 is provided with a discharge cover body 14 covering the lower periphery of the discharge port 12 formed at the tip of the discharge port body 11. The discharge cover body 14 guides the grains coming out of the discharge port 12 downward, and the tip of the discharge cover body 14. A guide plate 15 for guiding the grain along the inner side of the side wall F is provided, the guide plate 15 can be pivoted away from the front side wall F with the upper end portion serving as a fulcrum 16, and the guide plate 15 can be rotated. Since it is configured so that the grain discharge direction can be changed to the auger base side by changing the moving position, the grain discharge direction is changed to the auger transfer direction in the discharge cover body 14 with a simple configuration. Possible Ri, the grains after being discharged to the bed of the truck operator effort leveling is reduced. And even if the grain leaks from the gap between the guide plate 15 and the left and right side walls L, R of the discharge cover body 14, the grain is guided downward by the front end side wall F of the discharge cover body. Can be prevented from falling off the cargo bed.
Further, a guide plate automatic rotating means for periodically reciprocatingly rotating the guide plate 15 with its upper end portion as a fulcrum 16 is provided, and the operation of the guide plate automatic rotating means is turned on and off. Since the operation of the discharge auger 11 is turned on and off when the grain is discharged, the automatic operation of the guide plate automatic turning means is automatically turned on and off, so that the guide plate 15 is manually reciprocated. There is no need for rotational driving, and there is no need for turning on / off the operation of the guide plate automatic turning means, further reducing the labor of the operator.

  The grain discharge switch 25, the guide plate automatic rotation switch 31, and the guide plate manual rotation switch 32 are provided at a place other than the control section 7 so that it can be operated by an operator at a place other than the operation section 7. For example, you may arrange | position at the front-end | tip part of the discharge auger 11. Moreover, you may comprise by things like a radio | wireless machine (remote control) which can carry out radio | wireless operation of an auger.
